To all whom it may concern:

Be-it known that I, PHILIP H. F rmnnve, residingat SouthNorwalk,=cou'nty of "Fair.- field, State of Connecticut, a citizeniofthe United States, have invented certain; new;

and useful Improvements Timer pCovers,

of'which the following is a specification." l

This invention relates to covers for timers and the likeand-particularly to those timers having terminals exposed to dirt, oil,water.

moisture or :corrosivevapors. v

The primary ob1ect of my invention is to vapor orother foreignsubstances. 7 Another obj eet of invention is the provision of such acover forthe't'erminals that a resilient. pressure is maintained betweenthe. edge of the timercover and the timer,

thereby substantially'maintaining a water tight" cover for theterminals.

A further object'of my invention li's the provision of a flexible waterproof cover for. terminals of timers. and the like which can easily beinstalled and removed.

Referring to the drawing where preferred embodiments of my invention areillustrated, Figure 1 is an elevational view of a timer body having myinvention installed thereon.

Figure 2 is a partial cross section on the line 2-2 of Figure 1.

Figure 3 is a crosssectional View taken on the line 3-3 ofFigure 2.Figure t is an elevation, partly'in section, of a modified form ofm'yinvention. t I I Figure 5 is a View of the cover shown in Fig. 4in'its open position.

Figure 6 is affragmental cross sectional view on the line 66 of Fig. 3.

Like reference characters refer to similar parts throughout the severalviews.

, 1O designates a timer having a perforated arm 11 which is connected toa rod (not shown) which controls the degree of spark advance of aninternal combustion motor.

motor. The respective terminals are connected to their spark plugs inthe end of the corresponding cylinders by wires 12,

13 14' and 15. These wires pass from the timer through the conduits 12",13' and 15 the cable connections. Y Referring now particularlyto-Figures 1,2 and'S, 20 designatesthe body portion of my coverifor thetimer terminals and is prefer ably made of soft rubber or some similarmaterial. Enlarged portions .21, 22 and-23' are provided and haverecesses'to receive the [terminals 12, 13 and 15, respectively. -LA

cylindrical cable receiving member 24, in

vtegral with, and of the sainematerial as the zbody po'rt1on20, isprovided to receive the cable 16 and is 'h'ereshownas being spaced so-asvto'be adgacentitheterminal:14 tojreceive. the same when 1n positroni sIni-Ithe form shown in Figures 11 to. 3,"-I have shown .a spiit in thecable receivingniemberas'at 25' (Fig. 1) and ajolampi26 is "provided tohold-the 'two' portions of-ithe cable receiving member together andagainst A portion 27 of'the body-portion 2O lying adjacent the arm 11may be tmade'thinne'r than the other portions of the cover, since itdoes not contain any conduits ,forholding the wires; This portion ismade narrower j to the cable' 16 and thence to their proper Y than theother portions to clear the arnrll. i

In practice, I prefer to construct the body portion 20 slightly shorterthan the outer circumference of the timer in order that when it is putin place, it will be stretched and consequently'will make a water tightfit with the timer. j I

' where a modified- In Figures 4: and 5, form of my invention isillustrated, the parts 20*, 21, 22 and 23 correspond to thesimilarparts20, 21, 22 and 23 of Figs. 1, 2

and 3. The part 24 differs from. thepart '24: in that its halves aremade integral.

The modification shown in Figs. 4 and 5 may be made like that showninFigs. 1 to 3,

but made in a solid piece circumferentially.

4 and'5, the cable 16 and its wires are passed through the cylindricalportion 24:.after '1 0'.

which the Wires are connected to the respective terminals 12, 13, 14 and15.; The body portion 20 is then put in place under tension and theclamp 29 applied to the ends 27 of the thin portion. The screws 30 arethen put in place to hold the timer cover in place. 7

If the modification shown in Figs. 4 and 5 is made in a solid pieceeircumterentially, in the form of a closed ring, the cable 16 and itsWires are passed through the cylindrical portion 241, after which thew'rcs are connected to the respective terminals. The bodyrportion isthen forced down to position and is thereby slightly stretched, thetension and friction holding it in place.

Although I have described embodiments of my invention in detail, Idesire to have it understood that I do not limit myself to the exactconstruction'shown and described and that modifications and changes maybe made Without departing from the spirit of the invention and withinthe scope of the appended claims.

Having described my"invent.ion, What I claim is: v

1. A terminal cover for timers compris ing a softflcxible body portion,the body portion'comp'risinga band portion to substantially surround theouter periphery oil? the timer and having spaces to receive the timerterminals.

2. A terminal cover for timers comprising a soft flexible body portion,the body portion comprising a band portion to substantially surround theouter periphery of the timer and having spaces to receive the terminalsand spaces for the lead wires lead ing to the terminals.

3. A terminal cover for timers comprising a soft flexible body portion,the body portion having spaced enlarged hollow portions adjacent thecorresponding positions of the terminals of a timer and to cover thelatter, the body portion having also an opening to receive the leadwires and spaces for holding the lead Wires and connecting the openingand the hollow portions.

4. A. terminal cover for timers comprising a flexible body portion, thebody portion having spaces to receive the timer terminals, and spacesfor the lead wires leading to the terminals, and a cylindrical portionto receive a cable carrying the lead Wires to the terminals.

5. A terminal cover for timers compris-- ing a body portion, the bodyportion having spaced enlarged hollow portions adjacent thecorresponding positions of the terminals of a timer and to cover thelatter, the body portion having, also an opening to receive the leadwires and spaces for holding the lead wires and connecting the openingand the hollow portions, the body portion terminating in twosemi-cylindrical complementary members in a position to enclose one ofthe timer terminals and a portion of the cable carrying the terminallead wires.

In testimony whereof I hereunto ailix my signature.

PHILIP H. FIELDING.
